[0002] In the healthcare industry, people often encounter a disease in which the patient's hand muscles have neurological lesions, such as cerebral palsy, stroke, and other diseases in which the active motor nerves are damaged. Due to the damage to the patient's active motor nerves, the active movement of the muscles controlled by the nerves is impaired, or the active movement function disappears completely. For such patients, in the process of rehabilitation medicine, while controlling the disease with drug treatment, it is also necessary to promptly carry out auxiliary movement therapy for the organs with motor dysfunction to avoid atrophy of the corresponding organ muscles, resulting in loss of muscle tension, and ultimately leading to flaccid paralysis or dynamic deformity, affecting the patient's rehabilitation effect. Among the common rehabilitation medicines currently available, the most common is the rehabilitation of patients' hand lesions and deformities. In rehabilitation treatment, people often use various auxiliary rehabilitation equipment to make the patient's diseased fingers stretch and grasp as much as possible, so as to properly train the muscles and hand joints to avoid muscle atrophy in the end.

The finger fixing plate 9 is hinged to the hand fixing plate 2 through the cooperation of the rotating groove 24 and the rotating shaft 13;

[0044] Through the cooperation of the second airbag 6 and the connecting tube 7, the gas inside the second airbag 6 is squeezed into the first airbag 5, and the hand fixing plate 2 is supported by the first airbag 5 to be raised and lowered. When the hand fixing plate 2 is raised, the hinged finger fixing plate 9 will bend, thereby achieving exercise for the palms and fingers.

[0045] Embodiment three:

[0046] like Figure 4-6 As shown, the structure of the hand rehabilitation exercise device disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0047] A second engaging block 15 is fixedly disposed inside the rotating groove 24, and the second engaging block 15 is in a semicircular ring structure. A matching first engaging block 14 is fixedly disposed at a position of the rotating shaft 13 corresponding to the second engaging block 15, and the first engaging block 14 is in a quarter ring structure.

[0048] The second engaging block 15 is provided with a receiving groove 16 at one end thereof for resisting against the first engaging block 14 for rotation, a matching resisting block 17 is slidably disposed inside the receiving groove 16, and a supporting rod 18 is fixedly connected to one end of the resisting block 17;

[0049] A through slot 19 is formed inside the rotating slot 24 at a position corresponding to the support rod 18, and the through slot 19 passes through the hand fixing plate 2;
